摘要
为探讨质子在人体组织(或组织等效介质)中能量沉积微观特性,在对人体组织材料进行分析的基础上,确定水蒸气作为组织等效材料。利用蒙特卡罗粒子输运技术模拟质子在介质中的微观行为。通过计算数据分析可知,质子在介质中主要以小能量沉积事件(0～50eV)发生能量沉积,这些小能量沉积事件组成质子径迹。
In order to research the energy deposition micro-specialty of proton in body-tissue or tissue equivalent material, the water vapor was adapted to be the tissue equivalent material based on the analysis of the body-tissue. The Monte-Carlo method was used to simulate the behavior of proton in the tissue equivalent material. The value in every energy deposition event is in the range of 0-50 eV by analyzing the data from calculation. The proton track is composed of these energy deposition events.
